What is this?

NAIROBI, Kenya – The Kenyan government over the weekend said it will bar passengers travelling from three West African countries hit by the Ebola outbreak, closing a debate in East Africa’s economic powerhouse about whether the national airline was exposing the country to the deadly disease.

The suspension is effective midnight Tuesday for all ports of entry for people travelling from or through Sierra Leone, Guinea and Liberia, said Kenya’s Health Ministry. Nigeria was not included in the ban, which also allows entry to health professionals and Kenyans returning from those countries.

“This step is in line with the recognition of the extraordinary measures urgently required to contain the Ebola outbreak in West Africa,” the Health Ministry said. It cited the World Health Organization’s recent statement that the magnitude of the Ebola outbreak has been underestimated.

Following the government’s announcement Saturday, Kenya Airways said it would suspend flights to Liberia and Sierra Leone. Kenya Airways, a major transport provider in Africa, has wrestled with the decision whether to continue flying to West Africa during the Ebola outbreak. Its suspension of flights is an abrupt reversal of its announcement Friday that it would continue flying.

Social commentators, medical experts and Kenyan politicians said they feared the airline was putting profits ahead of prudence, and that KQ, as the airline is known, would spread Ebola. The airline flies more than 70 flights a week to West Africa, but chief executive Titus Naikuni told a news conference Thursday that airline’s flight decisions had nothing to do with money.

The airline said flights actually help to contain the Ebola outbreak by transporting medical staff, supplies and equipment to West Africa.

But doctors representing the Kenya Medical Association had asked Kenya Airways to suspend flights to the four countries affected by Ebola “until things stabilize.” Members of parliament also called on the carrier to halt its West African operations.

Several airlines have already suspended flights to Sierra Leone, Guinea and Liberia, including British Airways, Emirates Airlines, Arik Air and ASKY Airlines. Nigeria became the fourth Ebola-affected country late last month after a Liberian-American man sick with the disease flew to Lagos on an ASKY flight and infected several people before he died.

Officials in Cameroon, which borders Nigeria, announced Friday it would suspend all flights from all four Ebola-affected countries. Korean Air announced on Thursday it would temporarily halt its service to Kenya despite the fact there are no cases of Ebola in the country.

The World Health Organization has denounced the travel bans. The virus has a low transmission risk during air travel, since it is spread via bodily fluid and is not airborne, said Isabelle Nuttall, director of the organization’s Global Capacity Alert and Response. Her statement came a day after the organization classified Kenya as a high-risk country for Ebola transmission, citing its status as a regional transport hub.

“When decisions are made by airline companies, they have to take into consideration their perceived risk and the real economic impact on countries that are already affected by a disease they have to control,” Nuttall said Thursday in Geneva.

Ebola-affected countries are suffering economically as international airlines restrict flights, companies scale down regional operations and much commercial trade is put on hold, said the World Bank. The bank, with the International Monetary Fund, reduced this year’s economic growth estimate for Guinea to 3.5 per cent, down from their original projection of 4.5 per cent growth.
